The three questions to ask any BBL surgeon before you send a deposit
The wire instructions just landed in your email. Before you hit send on a $2,000 deposit for a surgeon you've never met, ask these three questions. Here's what the right answers sound like — and what to do when they don't.
It's 8:47 PM on a Tuesday. The wire instructions just landed in your email: Banco de Bogotá, an account number, a beneficiary name you don't recognize, an amount you converted from Colombian pesos three times just to be sure. Two thousand dollars. Non-refundable. The clinic wants it by Friday to lock your surgery date in seven weeks.
Your cursor is hovering over "send" on your bank's transfer page. You've done the research. You've watched the YouTube walkthroughs, read the r/PlasticSurgery threads, looked at the before-and-afters on Instagram. You've had three WhatsApp exchanges with the coordinator. Everyone was friendly, prices were fair, the surgeon has 87,000 followers.
You still don't feel great about hitting send.
Good. That feeling is doing you a favor. Because before that $2,000 leaves your account, there are three questions you haven't asked yet — and the answers to those three questions will tell you more about whether this surgeon should be putting fat into your body than every review, every follower count, and every airbrushed before-and-after combined.
Why three, not ten
The internet loves a checklist. "20 questions to ask your plastic surgeon" pops up on every consultation-prep blog. Most of those lists are noise — questions like "how long will I be swollen?" and "what's your bedside manner like?" that don't actually protect you from anything. They're the kind of questions that let a bad surgeon give you 20 comforting answers.
What you need instead are the questions where a bad answer is disqualifying. Where the wrong response means you thank them for their time, walk away from the deposit, and start over. Questions where the answer is either right or it isn't — no room for charm, no room for "well, it depends on the patient," no room for the coordinator's smile to smooth over what the surgeon just told you.
Three questions do that job. If a surgeon answers these three correctly, they've cleared the bar that most industry insiders — including the Colombian plastic surgery society itself — consider non-negotiable for a Brazilian Butt Lift in 2026. If they hedge on any of the three, keep the $2,000 in your account and start the search over.
The three questions aren't about whether you'll like your result. They're about whether you'll come home alive.
Here they are, in the order you should ask them. Then we'll walk through why each one matters, what a good answer sounds like, and what to do when the answer is bad.
The three questions
1. Are you performing a subcutaneous-only BBL, and do you use ultrasound guidance during the fat transfer?
2. How many BBLs did you personally perform in the last twelve months, and can you send me your ReTHUS registration number?
3. Which hospital will my surgery take place in, and what's its JCI accreditation status?
Question 1: The subcutaneous-only question
This is the single question that matters more than every other question combined. The BBL has been the most dangerous cosmetic procedure in the world since about 2015, with a mortality rate that a 2017 Aesthetic Surgery Journal study estimated at 1 in 3,000 — orders of magnitude higher than any other elective cosmetic surgery. The reason for that mortality rate is a single technical decision the surgeon makes with the fat-transfer cannula: whether they inject the fat into the muscle, or only into the layer of tissue above the muscle.
Injecting into the muscle — the gluteus maximus, specifically — puts the cannula close to a network of large veins that drain the buttock. If the cannula punctures one of those veins, fat gets injected directly into the bloodstream. That fat travels to the lungs. That's a fatal pulmonary fat embolism, and it can happen on the table or in the recovery room within hours.
Injecting only into the subcutaneous layer — the fat between the skin and the muscle — avoids that vein network almost entirely. In 2018, a joint task force from five plastic surgery societies (including the American Society of Plastic Surgeons and Colombia's Sociedad Colombiana de Cirugía Plástica) issued formal guidance: subcutaneous injection only, no exceptions. Since then, the mortality rate for BBLs done by surgeons who follow that guidance has dropped dramatically.
What a good answer sounds like
The answer you want
"Yes. I only inject in the subcutaneous plane — never in the muscle. I use intraoperative ultrasound to verify the cannula depth in real time throughout the procedure. If you want, I can send you a photo of my ultrasound setup."
The answer that ends the call
"We adjust the technique based on the patient's anatomy." Or: "Subcutaneous mostly, but sometimes we go a little deeper for better projection." Or the coordinator answers on the surgeon's behalf.
The ultrasound piece matters more than most patients know. Even a surgeon who intends to stay in the subcutaneous plane can drift into muscle during a long procedure — the tissue planes shift as fat is added, and the cannula tip is invisible. Intraoperative ultrasound gives the surgeon a live view of exactly where the cannula is at every moment. It's the single biggest safety upgrade in BBL technique since the 2018 guidelines, and any surgeon doing high-volume BBL in 2026 should be using it.
If they say "I don't use ultrasound but I've done thousands of these and I know where the muscle is by feel," that's still a bad answer. It's the medical equivalent of a pilot saying they don't need instruments because they've flown the route a thousand times. Feel is not a substitute for a live picture of where your fat is going.
The vetting rule
Non-negotiable across every partner clinic on Book Colombia Medical: subcutaneous-only fat placement, no exceptions. If a surgeon can't or won't confirm this in writing before your deposit, we don't send patients to them, and neither should you.
Question 2: The volume + ReTHUS question
This question does two jobs at once. The first half — the volume question — separates surgeons who do occasional BBLs from surgeons whose practice centers on the procedure. The second half — the ReTHUS ID — verifies that the person answering is actually a licensed Colombian medical practitioner.
The unofficial threshold that most Colombian plastic surgery insiders use is 100 BBLs per year. Below that, complication rates climb noticeably — not because the surgeon is bad, but because BBL is a procedure where hand-eye calibration matters and volume keeps the calibration sharp. Above that, complication rates flatten out. A surgeon doing 200–400 BBLs a year is in the zone where technique becomes muscle memory.
The ReTHUS check — why it's not optional
ReTHUS is the Registro Único Nacional del Talento Humano en Salud — Colombia's national registry of licensed healthcare professionals, maintained by the Ministerio de Salud y Protección Social. Every legitimately practicing physician, nurse, and dentist in Colombia is in it. The registry is public: anyone can search a name and see the registration status, license number, and specialty certifications for any registered practitioner.
Asking for a surgeon's ReTHUS number does two things: it verifies they're licensed, and it signals to the clinic that you're a patient who knows how the system works. Legitimate clinics are used to this request. Illegitimate ones react badly.
How to actually verify a ReTHUS number in 90 seconds
- Go to the Ministerio de Salud y Protección Social website and search for "ReTHUS consulta pública" (or search that phrase directly in Google — the public consult tool has moved between subdomains a few times).
- Enter the surgeon's full name and document type. Colombian surgeons use a Cédula (CC) or Cédula de Extranjería (CE).
- Confirm three things: (1) they're registered, (2) their specialty registration includes plastic and reconstructive surgery (Cirugía Plástica y Reconstructiva), and (3) the registration is active — not suspended, expired, or under review.
- Cross-check their board certification with the Sociedad Colombiana de Cirugía Plástica (cirugiaplastica.org.co). Board membership isn't legally required to practice, but the absence of it in a high-volume BBL surgeon is worth asking about.
The answer you want
"Last year I performed 312 BBLs — I can show you the anonymized case log if you want to see the distribution. My ReTHUS number is [number]. Verify it on the Ministerio de Salud site. I'm also a certified member of the SCCP; membership number is [number]."
The answer that ends the call
"Hundreds. Our clinic does a lot of BBLs." (Deflects from personal count to clinic count.) Or: "I'll have the coordinator send that over." (And then it never arrives.) Or: "Why do you need that?"
The "our clinic does a lot" answer is the specific one to watch for. It's a way to inflate volume without answering the actual question. Clinics don't perform BBLs. Individual surgeons do. If the surgeon isn't personally clocking 100+ per year, the clinic's aggregate number is irrelevant to your safety.
Question 3: The hospital + JCI question
BBLs are not simple procedures. They involve general anesthesia for four to six hours, significant fluid shifts, and — in the rare event of a complication — potential need for immediate ICU access. That last piece is why the "which hospital" question matters. A cosmetic clinic with an on-site OR is not the same thing as a hospital with an ICU one floor away.
What JCI is, and why it's the standard to ask about
Joint Commission International is the international accreditation arm of the same body that accredits U.S. hospitals. It's a rigorous, expensive, voluntary certification — hospitals go through it to signal to international patients and insurers that they meet a global standard for patient safety, infection control, medication management, and clinical governance. Colombia has 14 JCI-accredited hospitals as of 2026, including Fundación Valle del Lili in Cali, Hospital Pablo Tobón Uribe in Medellín, Fundación Santa Fe de Bogotá, and Clínica Las Américas Auna in Medellín.
JCI accreditation isn't strictly necessary — a hospital can be excellent without it. But asking about it is a fast way to sort surgeons who operate in hospital-grade facilities from surgeons who operate in stand-alone cosmetic clinics with converted procedure rooms. For BBL specifically, the stand-alone-clinic route adds real risk: less anesthesia depth, no ICU escalation path, sometimes no on-site blood bank.
The answer you want
"Your surgery will be at [named JCI-accredited hospital]. Their JCI status is current; you can verify it on jointcommissioninternational.org. The anesthesiologist assigned to your case is [name], also ReTHUS-registered — I can send their number too."
The answer that ends the call
"Our own clinic — we have our own surgical suite." Or: "One of the top hospitals in Medellín" (unnamed). Or: "The hospital changes depending on the day, we'll confirm closer to your surgery date."
The named anesthesiologist matters too. In Colombian cosmetic surgery, the anesthesiologist is a distinct hire — not a hospital employee — and their credentials are yours to verify separately. A surgeon who names their anesthesiologist without being asked is a surgeon who knows you're going to check.
The questions you should not ask
Some of the most common consultation questions are actively counterproductive. They put your surgeon in a position where the right answer is not the one you want to hear, and they can nudge the whole conversation toward marketing instead of medicine. A few to skip:
"How many cc's are you going to inject?"
This is a clinical judgment made intraoperatively based on how your specific tissue accepts the fat, how much fat is available from your donor sites, and how much your anatomy can safely hold. Pre-negotiating a number invites the surgeon to hit that number even when their intraoperative judgment says they shouldn't. The right answer to "how much fat will you transfer" is "as much as your tissue can safely accept — I'll evaluate that live."
"Can you guarantee my result will look like [Instagram photo]?"
No ethical surgeon guarantees a specific aesthetic outcome from a body-contouring procedure. Fat retention rates vary from 40% to 80% patient-to-patient, and your final shape depends on your donor site distribution, your skin quality, your recovery discipline, and factors nobody can predict. A surgeon who guarantees your result is a surgeon who is lying to close a sale.
"Can I combine BBL with lipo of arms, thighs, and abdomen at the same time?"
You can, but you probably shouldn't. Combined procedures push total operating time past six hours, dramatically raise cumulative fluid loss, increase anesthesia risk, and complicate recovery. The 2018 multi-society BBL guidelines specifically flag combined procedures as an elevated-risk category. A surgeon who enthusiastically says yes to any add-on you propose is showing you their business priorities.
How to actually verify in Colombia — the practical guide
The three questions produce answers. The answers need to be verified. Here's what to actually do, in the order to do it, on the same day you get the answers:
ReTHUS lookup
Search "ReTHUS consulta pública" on Google. The Ministerio de Salud tool is the top result. Enter the surgeon's full name and Colombian document number (Cédula de Ciudadanía for Colombian nationals, Cédula de Extranjería for foreign-born practicing physicians). Confirm active registration and specialty in Cirugía Plástica, Estética y Reconstructiva.
SCCP membership check
Go to cirugiaplastica.org.co. Use the member directory. SCCP membership is voluntary but is the strongest Colombian board-certification signal for plastic surgery specifically. A surgeon doing high-volume BBLs who isn't in the SCCP is worth a follow-up question.
JCI hospital verification
Go to jointcommissioninternational.org and use the "Find an accredited organization" search. Filter by country: Colombia. You'll see the current list of 14 accredited hospitals. Match the hospital name against what your surgeon told you.
Anesthesiologist check
Run the same ReTHUS lookup on the anesthesiologist's name. Confirm active registration and specialty in Anestesiología. This takes 60 seconds and it's the single most under-done verification step in cosmetic tourism.
The 20-minute total verification
All four checks above — ReTHUS on the surgeon, SCCP on the surgeon, JCI on the hospital, ReTHUS on the anesthesiologist — take roughly 20 minutes if you have the names in front of you. There is no better use of 20 minutes anywhere in the medical tourism process. Do them before you send the deposit, not after.
When to walk away — and how
What happens when the answers are bad? The temptation, especially after you've spent weeks researching this clinic, exchanged 40 WhatsApp messages with a friendly coordinator, and rearranged your work calendar around the surgery date, is to rationalize. "Well, they didn't say they don't use ultrasound." "Maybe they meant the clinic's volume as a proxy for their own." "I'm sure their anesthesiologist is good even if they wouldn't share the name."
Don't rationalize. The three questions exist precisely because the sunk cost of research and rapport is what makes patients push through red flags they'd never accept from a stranger. If a surgeon fails one of the three, here's the script:
"Thank you for the detailed answers and for the time your team has spent on my case. I've decided to book with a different surgeon and I won't be sending the deposit. I wish you and your team well."
That's it. No debate, no negotiation, no request for a discount. You don't owe a bad-answer surgeon an argument. Cancel the wire, send the message, and start the search over. The seven weeks between now and your original surgery date is enough time to run the three questions on three new surgeons and pick the right one.
What good actually looks like
To give you a concrete picture of a full pass-through — this is a composite based on how a well-run vetted-clinic exchange typically goes, not any specific real case:
You send the three questions on a Wednesday morning. By Wednesday afternoon, you have a WhatsApp voice memo from the surgeon (not the coordinator) answering all three, in order. She names the subcutaneous-only technique and describes her ultrasound setup. She gives her BBL volume for the last twelve months as a specific number (in the 250–350 range) and offers her ReTHUS registration number in the same message. She names the hospital — one of the 14 JCI-accredited facilities — and offers to send the anesthesiologist's name and ReTHUS number too.
You spend twenty minutes verifying. All four checks pass. You send the deposit Wednesday night.
Two weeks before surgery, the coordinator sends a pre-op packet with the anesthesiologist's contact info, the hospital admission process, a list of medications to stop, and a recovery-friendly stay recommendation in a specific neighborhood — never on a short-term vacation rental platform, because most partner clinics steer patients toward serviced recovery apartments with medical-tourism experience. You arrive in-country three days early to acclimate. You meet the surgeon in person the day before surgery, in a scheduled consult where she confirms the plan and answers any last questions. You get through surgery, spend a night in the hospital, transfer to your recovery stay, get post-op massages on a schedule, and fly home twelve days later.
That's the flow when the three questions come back right. Everything downstream — recovery, result, follow-up — gets easier when the answers upstream were the ones you wanted to hear.
The three-question checklist, for a bookmark
Before you wire the deposit
- Ask question 1 — subcutaneous-only fat placement, intraoperative ultrasound. Confirmed in writing.
- Ask question 2 — surgeon's personal BBL volume for the last 12 months (target 100+), plus their ReTHUS registration number.
- Ask question 3 — named JCI-accredited hospital where the surgery takes place, plus named anesthesiologist with their own ReTHUS number.
- Verify all four — ReTHUS on surgeon, SCCP directory on surgeon, JCI directory on hospital, ReTHUS on anesthesiologist. 20 minutes total.
- Walk away from any hedge — no ultrasound, no personal volume figure, unnamed hospital, or refused credentials means the deposit stays in your account.
- Confirm the recovery-stay recommendation is a medically-oriented apartment, not a random short-term vacation rental.
The last thing
The three questions aren't a trap for surgeons. They're a filter. Any surgeon whose practice is built around BBLs done safely will answer them without hesitation and often before you finish asking. Any surgeon who bristles, deflects, or lets the coordinator answer for them is telling you something important about the practice you're about to buy into.
The deposit is $2,000. The stakes downstream — the surgery itself, the recovery, the two weeks in a foreign country, the years living with the result — are much higher. Twenty minutes and three questions is not a lot to spend on the checkpoint before all of that begins.
Ask the questions. Verify the answers. Then wire the money, or don't.
